Just purchased the cord and performed all recommended steps. Lost a blade last week trying to fly while it was still acting strange. When new blade comes in mail I will update you. Everything seems status so far. Thank you for all your help
QUOTE="J Dot, post: 987154, member: 9673"]Hello,
Cable is a ( USB, to MINI-USB ) same as used by most common cell phones.the red lights can mean several things.
1) critically low battery
2) non-intelligent DJI battery
3) CMOS error ( IMU error )
4) compass error
When motors start you should see solid red front lights, and blinking ( yellow ( 5 or less satellites )or green ( 6 or more satellites ) in the back arms.
Being it is a used craft, there are some things you will need to do.
( I'm not Mac computer savvy , as I'm a PC person, but below should be the same once hooked up.)
1) hook Tx to ( RC assistant )
Perform a complete calibration
( if you have an older Tx without sub plug, you must open Tx to leave cate the hidden internal use port inside tx newer models have an external use port. )
1). Both sticks
2) s1/s2 toggles
3) dial wheel or 7th channel mod ( if avail. )
This will calibrate your Tx
2) hook phantom to PC Assistant,
Under basic/RC tab
Calibrate Tx here again ( both sticks, s1, and dial wheel/7th channel mod
( this will calibrate Tx to your bird )
3) while still hooked to PC assistant, ( with bird LEVEL all directions and stationary ( no wobbling around ) perform an advanced IMU calibration.
4) do a fresh compass calibration
This should bring your bird back to factory settings, and fly stable, and sit still, with little drift.
If there is still an issue, we will focus on that after you perform these tasks. Don't sell it too soon, we can get you fixed up, it's not hard. I'd be happy to help.
Keep us updated.
